1 ½” Bearing LengthLoad Span Tables Based on Working StressFlexural Design analysis according to AISI “Speci�cation for the Design of Light Gauge Cold-Formed Steel Structural Members” May 1981Continuous Span Loading applies to sheets continuous over three or more spansWeight of sheet has not been allowed for when calculating live load and Uplift.De�ection (L/180) limiting live load based on de�ection of span.Metal thickness based on minimum ASTM speci�cations for allowable load calculationsLoads may be increased by 1/3 for wind loads
Areas of discontinuity are subject to higher spikes in wind pressure, therefore a di�erent coe�cient in wind pressure will need to be considered and multiplied by a factor of 1.5
Data from: 1994 UBC Table 16-F
Note: The load tables have been compiled for the design of steel roo�ng and siding used in conjunction with either wood or steel framed structures. Teton Steel assumes no responsibility, either expressed or implied, for its use.
Gauge: 28
Weight: 1.5 lb. /LF
Steel Yield Stress: 50,000 psiGalvalume Steel Gauge, AZ-50
Paint System: Stormshield Xt-40, Energy Star® Rated, Silicone Modi�ed Polyester
Warranty: 40 Years
Available Material Type:Painted, Galvalume®
Gauging System: Teton Steel follows the national A.I.S.I. (American Iron and Steel Institute) speci�cations manual for tolerances in galvanized sheet metal.
All gauges conform to ASTM A792 and A653 Grade D (50,000 min. yield) unless otherwise speci�ed at the time of the order.
Minimum Slope Requirement: 3:12
Screw Application: #10 Wood grip fasteners are designed for use with dimensional lumber, #14 Wood grip fasteners are designed for use with plywood sheeting, OSB, and wafer wood (7/16” minimum thickness). #12 Tek screws are designed to be used with structural steel up to 3/16” in thickness.
Roof Application: Fasteners to be applied along side every rib and attached to each purlin, 2’ on center. Please note that it is the responsibility of the builder to ensure that purlins are adequately spaced to meet speci�c engineering requirements.
Teton Steel is neither partially nor solely responsible for improper installation or defects as a result of installation.
